IS

She told everyone she was sick. She never told them why. Y/N has always been the person who keeps her problems to herself. Even with Bucky Barnes, the one person she trusts enough to tell everything. Except for one secret. For months, Y/N has been silently dealing with a condition that leaves her struggling through pain she refuses to explain. One night at the Avengers Tower, that secret finally catches up with her. When Bucky finds her alone on the kitchen floor, he immediately knows something is wrong. And for the first time, Y/N can’t hide it from him. Sometimes the person who knows you best is the one person you never meant to find out.
